I could not figure out how to review the play list in Clown BD. Do I have to render the entire play list to be able to view the introduction so I can see if it is the correct playlist?
I thought it might not be obvious when I wrote my post, but didn't want to belabor an already long reply with more details about how to use Clown_BD.
When you run Clown_BD it basically has three steps. Step 1 is to choose the drive to render from, file paths to eac3to and the other tools it uses under the hood, etc. Step 2 is to choose the playlist to render. And then Step 3 is to choose exactly which video, audio, and subtitle tracks from that playlist to render.
If you look at the screenshot of Clown_BD that I posted, it shows you Step 2 where it lists the playlists it thinks are candidates for the main movie. For each of those playlists it then in the square brackets lists out the individual m2ts files that make up that playlist.
Number 1) is playlist 00802.mpls and is made up of [301.m2ts, 321.m2ts, etc.]
Number 2) is playlist 00801.mpls and is made up of [301.m2ts, 310.m2ts, etc.]
In order to play those m2ts files without rendering the movie out, you simply have to open Windows Explorer, navigate to the files on the drive/ISO that you're rendering from (you have to right-click and select Open, as the default action in Windows Explorer is to try to autoplay anything it considers media or disc content), go into the BDMV\STREAM folder, as I mentioned, and find the individual m2ts file in the list. Just like locating and viewing a particular picture in your My Pictures folder. If you're not familiar with basic file operations in Windows, then I'm afraid you might be swimming in water above your head, so to say... The only other thing to say is that you need to have an application that's able to play m2ts files, such as VLC, or Media Player Classic-Home Cinema (MPC-HC, which I mention in my first reply), or something similar.
I guess one more thing I could say is that a blu-ray playlist file (.mpls) is nothing more than a listing of what individual media files (.m2ts) make up that playlist. You don't need to render anything to see what files are contained in a playlist. (If you're able to handle all the extra info, then the program BDInfo does exactly that -- it shows you the playlists and what they consist of, and pretty much does nothing else. BDInfo is also mentioned in my original reply.)
